sash is there, along with ash.static. Hmmm.
Odd. It seems that su refuses to run without libtermcap. There is, in
fact, a symlink ( /lib/libtermcap.so.2 -> libtermcap.so.2.0.8 ).
[robk at ningaui robk]$ su -c /bin/ash

Oh dear.

Hmmm, part two. No libtermcap there.

Down for me at the mo; I'll check tomorrow. Now for pizza and beer.

Well, to be fair, I did install a 6.0 update over the latest Rawhide,
which is probably a Bad Thing To Do.
